Custom Works details define this Equinox edition: a black Nitron slide with polished stainless flats, Equinox script, and the SIG Custom Works emblem. The slide is optics-ready with a cover plate, and it includes front and rear serrations for positive manipulation. Nickel-colored controls complement the two-tone finish, and the flat, skeletonized trigger is nickel-colored to match.
The AXG aluminum grip module delivers a metal-frame feel and includes an extended beavertail with checkered frontstrap and backstrap. The magazine release is checkered, and the pistol uses an ambidextrous slide catch. An M1913 three-slot accessory rail is integrated into the frame.
This striker-fired 9mm uses a 3.9-inch barrel and a standard 17+1 capacity with compatible magazines. Sights include a green-dot front marked TG-H3 and a serrated square-notch rear. The platform remains fully modular within the P320 family.
Markings include SIG SAUER INC., NEWINGTON-NH-USA on the frame and 9mm x 19 on the barrel hood. The included steel magazines comprise two flush-fit 17-round mags and four flush-fit 10-round restricted-capacity mags (some marked Made in Italy); no extended-length mags are included. As a limited-time Custom Works release in the Equinox series, this example represents a recent 2020s production from the USA.
